Hi,

A motor block (like MotL, MotSpdCL) has three interlocks: Permit, Interlock and Protect.

I think you need to use Permit.

When the motor is in idle (stopped), and Permit is "0", then the motor is not allowed to start. Only when Permit is "1", the motor starts (if the start command is given).

When the motor is running and Permit becomes "0", the motor will not stop. Whenever the motor is stopped, the motor only starts again when Permit is "1".

Is this what you want?

PS: Protect function is almost the same like the Interlock, but when motor is in Protect, you need to reset it first before it will start again.
